Description

A kind of quick transition dedicated trolley of tunnel widened section and construction method
Technical field
The present invention relates to Construction of Civil Engineering apparatus fields, and in particular to a kind of quick transition dedicated trolley of tunnel widened section And construction method.
Background technique
Band (widened section) the left and right line that stops in emergency is arranged altogether and amounts to 12 paragraphs, every segment length 50 for domestic section tunnel Rice.One section of band that stops in emergency of every 750 meters of settings on the right side of tunnel direction of traffic, four meters of width, 50 meters of length (including 2.5 × 5M changeover portion).
Super long tunnel in China's highway is all provided with the band that stops in emergency from safety considerations.Due to stopping in emergency Band Internal periphery bulk differ greatly with tunnel entirety cross dimensions, secondary lining trolley can not to lay-by position directly into Row one-piece casting, therefore traditional handicraft is new Working bogie or is transformed to secondary lining trolley to solve this construction hardly possible Topic.
Summary of the invention
The present invention is to solve existing band Internal periphery bulk of stopping in emergency to differ greatly with tunnel entirety cross dimensions, benefit The problem of one-piece casting can not directly be carried out to lay-by position to secondary lining trolley with traditional handicraft, and propose a kind of tunnel The quick transition dedicated trolley of widened section and construction method.
The quick transition dedicated trolley of a kind of tunnel widened section of the invention, composition include shell, multi-filament bar, support machine Structure and driving mechanism;
Supporting mechanism is hinged by multi-filament bar with inner surface of outer cover, and the bottom end of supporting mechanism is equipped with driving mechanism;
The shell includes top template, No.1 side template and No. two side templates;One end of top template and one One end of number side template is hinged, and the other end of top template and one end of No. two side templates are hinged, and top template, No.1 Side template and No. two side templates, which are constituted, has the semicylinder shape of cavity;
The supporting mechanism includes widening frame, crossbeam, oil cylinder, cylinder rack, increasing box, gusset and longitudinal support arm;
The both ends of crossbeam are respectively equipped with a longitudinal support arm, and the bottom end of longitudinal support arm connect with the one end for increasing box, increases The other end of box is connect with driving mechanism, and gusset is equipped between the inside of longitudinal support arm and the lower surface of crossbeam, longitudinal support arm It is equipped at outer side center and widens frame, the upper surface of crossbeam uniformly sets that there are two oil cylinders, and two oil cylinders are symmetrical arranged, two oil The output end of cylinder passes through cylinder rack and is fixedly connected with top template lower surface;
The driving mechanism includes motor and driving wheel, and the output end of motor is connect with big belt wheel, and big belt wheel passes through skin Band is connect with small pulley, and small pulley is coaxially connected with driving wheel;
Further, the driving wheel is equipped with groove along outer round surface;
The quick transition dedicated trolley construction method of a kind of tunnel widened section of the invention, detailed process is as follows:
Step 1: removing lower template and widening frame;
Step 2: removing door frame increases box;
Step 3: continuing to drop main top oil cylinder to 0 stroke, make trolley whole height lower than main hole contour line;
Step 4: replacement edge supports lead screw, a whole set of template is shunk within standard section:
Step 5: trolley axis is moved to tunnel middle line by the band middle line that stops in emergency;
Step 6: trolley is walked in tunnel to turning to area outside hole;
Step 7: longitudinal walking is switched to lateral walking turning to area;
Step 8: laterally running to another hole steering area, then become longitudinal walking manner by above-mentioned steps;
Step 9: starting two lining constructions to above step reverse operating after widened section;
Further, the step one, remove lower template and widen frame the specific method is as follows: widened section perimeter is greater than Standard section perimeter, it is necessary to remove the shrinkable section in lower template rear, method for dismounting is first to withstand lower template with long screw, later It removes hydraulic top and widens frame, finally remove lower template;
Further, it is torn open in step 2 and increases box the specific method is as follows:
Step 2 one, safety prevention measure prepare;
Step 2 two reduces oil cylinder;
Four groups of step 2 three, firm installation mechanic jacks are simultaneously held out against;
Box whole bolt is increased in step 2 four, release;
Step 2 five, jack synchronization of jacking up;
Box is increased in step 2 six, dismounting;
Step 2 seven penetrates long screw secure localization bolt in bolt hole;
Step 2 eight fastens long screw secure localization bolt while synchronous descending jack, after trolley lowers in place Jack and safety protection equipment are removed, replaces work bolt one by one on bolt hole;
Further, the retraction sequences of a whole set of template of contraction in the step four are shrinkage continuous yarn thick stick first, installation Short lead screw, and long lead screw is removed, short lead screw is then shunk, finally makes a whole set of template within standard section;
Further, trolley axis is moved to the specific method of tunnel middle line by the step five by stopping in emergency with middle line Are as follows: in widened section, by band angle vertical shift in a manner of realize that this is traversing, moved back one into one between, by trolley center line by widened section Center line moves on standard section center line, and drift angle size and vertical shift length are according between traveling wheel position limiting structure and rail flanges Away from being computed determination with traveling wheel longitudinal pitch;
Further, the walking manner of trolley is trolley automatically walk in the step six, and rail is had bad luck in artificial turnover Auxiliary, daily travel distance are 750m~850m, until walking to area is turned to, turns to area and requires the gradient within 0.5%, hole Arrangement and trolley transverse shifting;
Further, laterally walk that the specific method is as follows turning to area for longitudinal walking and switch in the step seven: After longitudinally running to steering area, steering operation is carried out, turns to step are as follows:
Step 7 one, safety measure installation, mechanic jacks synchronization of jacking up trolley;
Longitudinal running gear is switched to lateral running gear using steering box by step 7 two, installs laterally walking track, machine Tool jack backhaul;
It is fallen on cross moving track under step 7 three, trolley, removes jack and safety device, transverse shifting.
Compared with the prior art, the invention has the following beneficial effects:
One, the shortcomings that the present invention overcomes the prior arts, using No.1 side template, No. two side templates and top die benefit It is connected with hinged mode, No.1 side template and No. two outward trend of side template is made by way of being hinged, Inside is equipped with oil cylinder on girder, top template can be risen or be declined, and realizes the size that can expand or shrink shell, To be consistent with tunnel entirety cross dimensions.
Two, the present invention proposes new construction method, and the shell size for adjusting trolley is realized using step 1 to step 7, It to adapt to the size of tunnel inner wall, and move trolley can along tunnel, to solve secondary lining trolley to lay-by Position directly carries out the problem of one-piece casting.
Three, apparatus of the present invention are easy to operate, and construction method is also easy to operate.
